2.
Securely clamp the wire to the bottom of the mast.
3.
Secure the lead-in wire to a lightning arrestor and mast ground wire to the building with stand-off insulators spaced
from 4 ft (1.2 m) to 8 ft (1.8 m) apart.
4.
Mount the lightning arrestor as close as possible to the lead-in wire entry point on the building wall.
5.
Drill a hole in the wall as close as possible to the equipment to which you will connect the lead-in cable.
Caution: There may be wires in the wall. Make sure that you determine the place you intend to drill the hole is clear
of any obstructions or other hazards.
6.
From inside the building, pull the cable through the hole and form a drip loop close to where it enters the building.
7.
Thoroughly waterproof the lead-in area using an outdoor weather seal.
8.
Install a static electricity discharge unit.
9.
Connect the lead-in cable to the equipment. See the installation steps in the following chapters.
Note: Create a strain relief loop with a diameter of at least 0.75" (1.9 cm) for LMR240 cable or at least 1.75" (4.45
cm) for LMR400 cable at the cable/arrestor connection.
10.
Attach the lightning arrestor.
11.
Attach a second cable 25 to 50 ft (7.62 to 15.24 m) from the arrestor to the 3G-HWIC main antenna port. The total
maximum length of cable recommended is 75 ft (22.86 m) for LMR-240 cable and 100 ft. (30.48 m) for LMR-400
cable in areas with good outdoor signal reception. If this is not sufficient cable length for the application, a site survey
and the installer must calculate an appropriate link budget to determine the maximum cable length that can be used
for the specific installation.
